COMBINED HYDRAULIC MOTOR AND VACUUM-NOZZLE.

Specification of Letters Patent.

Patented Feb. 9, 1915.

Application filed December 6, 1913. Serial No. 805,052.

To all whom it may concern:

Be it known that I, NICK E. WILMES, a citizen of the United States,"residing in the city and county of San Francisco and State of-California, have invented new and useful Improvements in Combined Hydraulic Motors and Vacuum-Nozzles, of which the following is a specification.

This invention relates to a combined hydraulic motor and vacuum nozzle.

The purpose of this invention is to provide a simple, substantial, easily operated power unit, which is particularly adapted for use in connection with massage implements, such as vibrators, rubbers, and the like.

The object of the invention is to construct a single power unit provided with a hydraulic motor, a vacuum nozzle operable in unison with same, and a valve mechanism whereby either unit may be shut off from the source of pressure supply.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a side elevation showing the main power unit in which the hydraulic motor suction nozzle and connected parts are contained. Fig. 2 is a vertical, longitudinal section on line 2-2, Fig. 3. Fig. 3 is a central vertical cross'section on line 33, Fig. 1. Fig. 4 is a plan cross section on line 4.--4C, Fig. 3.

Referring to the drawings, A indicates a main casing, having a discharge opening 2 formed in the lower end thereof and an inlet opening 3 which opens into an upwardly extending chamber 4 adapted to receive the nozzle 5 of a faucet, a conical-shaped washer 6, and a suitable form of lock-nut, generally indicated at 7, for the purpose of retaining the washer within the chamber 4.

Journaled in bearings '7 having leakage grooves formed therein is a shaft 8, to which is secured a suitable form of impulse wheel 9, and formed on the side of the main casing A is an extension 10 having a cored passage 11 formed therein. The upper end of this passage communicates through an opening 12 with the source of pressure supply, while the lower end of same opens into the discharge end. of the housing A. The

extension 10 is also provided with a bib extension 13, near its upper end, to which a tube 14 may be attached, as shown. The inner end of the bib extension 13 opens into the passage 10 and the operation of same will be later described. 3

The two openings 3 and 12, forming communication between the source of pressure supply, the chamber 2 and the passage 10,

are conical shape in their upper ends, as indicated at 15, for the purpose of receiving a double-ended valve member 16 suitably secured, as at 17, upon a shaft or pin 18 extending through and journaled in the extension member 4 and having an operating handle 19 formed on its outer end. Leakage around this connection is guarded against by providing the usual form of stuffing-box connection, indicated at 20, similar means being provided around the main power shaft 8, as indicated at 21.

The power unit constructed as here shown may be quickly and easily attached to any standard form of faucet and is then ready for operation by simply turning the faucet valve to admit the water. If it is only desired to operate the impulse wheel 9 it is only necessary to swing the valve 16 into the position indicated in Fig. 3. This will prevent the escape of water through the passage 10 and will thus concentrate the full force of the water through the annularly positioned passage or nozzle 3 directly upon the face of the impulse wheel. Revolving motion will thus be transmitted to the shaft 8, which may be connected with the standard form of flexible shaft usually employed in connection with vibrating mas sage implements, rubbers, and the like. If it is desired to produce a vacuum, for instance when giving scalp treatments, in connection with the vibratory treatment, it is only necessary to move the valve into an intermediate position between the nozzle openings 3 and 12. The water is thus permitted to escape through both passages where one jet will actuate the vacuum nozzle while the other operates the impulse wheel. Similarly the whole force of the water may be concentrated upon the vacuum nozzle by swinging the valve into the dotted line position indicated in Fig. 3.

The power unit constructed as here shown is neat in appearance, may bequickly and easily attached to a standard form of faucet, and is always prompt and reliable in its actions.

The materials and finish of the several parts of the power unit are such as experience and judgment'of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims and that I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. The combination with a casing having a pair of chambers formed therein one for the reception of an impulse wheel and the other for a vacuum nozzle, of a pressure chamber formed in the casing, a water inlet to said pressure chamber, nozzle openings formed in the pressure chamber and communicating with the respective chambers, valve seats formed in the casing communieating with the nozzle openings, a swinging valve in the pressure chamber adapted to seat on either valve seat, and means external of the casing for swinging the valve from one position to the other, said valve entirely cutting off the water supply to either of the chambers.

2. In a hydraulic motor the combination with a casing having a pair of chambers formed therein, one for the reception of an U impulse wheel and the other for a vacuum nozzle, of a pressure chamber formed in the casing, a water inlet for said pressure chamber, nozzle openings formed in the casing communicating with the respective chambers, valve seats formed in the casing communicating with the nozzle openings, a rod journaled in the pressure chamber and extending through one side of same, a double-ended valve member secured to said rod adapted to seat in one valve seat or the other, and a handle on the outer end of the rod, said valve directing the water supply to either the impulse wheel or the vacuum nozzle.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
